UN IVERSAL SET TIN G GAUGE.

Applicationfiled February 16, 1927. Serial No. 168,734;

a gauge of thischaracter capable of ready manual adjustment, or operation with facility and expedition, and a gaugerwhich may be readily set upon any machine such for instance as the table of a planer and instantaneously adjusted to gauge the height of a planer tool.

Other objects of the invention are to provide a gauge of si1nple,practical construction which will be rugged, durable and accurate in use, and which may be manufactured with comparative economy. i

With the above noted and other objects in view, the invention consists in certainnovel features of; construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention maybe more fully understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a view partly in side elevation and partly in vertical section through the gauge of the present invention showing the same in use. i

Fig. 2 is a top plan view of the upper base block with the measuring rods removed.

Fig. 31 is a view partly in section and partly in side elevation of one of the measuring rods.

In the drawings I have used the reference character 10 to designate the table of a planer and 11, one of the planing tools, and showing the gauge of the present invention in properposition to gauge the height of the too V The gauge consists of a lower split annu: lar base bloc-1:12 formed with laterally projecting ears 13 through which is passed a screw 14 for contracting the lower base block to firmly clamp an upper base block 15 normally rotatable therein.

The lower base block is internally threaded as at 16, these threads preferably being arranged at such a pitch that the upper base block which screws into them, must be ro An object of the invention is to provide and tated four completerevolutions to complete an axial movement of one-haltinch relatively to the lower base block.v v

Upper base block 15 is formed with'a circular recess 17 sunkin its face, leaving the total width of block 15 from the surface of the recess to the bottom of the block12, one-half inch. When the block 15 has been screwed home in the block 12, an outwardly projecting flange 18011 the block 15 comes to reston the upper surface oi the block12 I acts as a stop. Hardened headless set screws 18 in the flange 18 take up the wear between the blocks 12 and 15. A graduated index post 19 rigidly connected to and laterally offset from the block 12, carries an inwardly projecting stop arm 20 projecting over thefiange 18. The distanee between the upper surface of the flange 18 and the lower surface of the arm 20 is graduated on the index post in cighths of an inch, so that the total'axial. movement of the upper base block 15 will be througha distance of one v half inch, and the upper base block must be rotated through four revolutions to travel this distance. p

K The stop a'rni' 20 andindex post 19 serve as a pointer enacting with a scale 21 displayed on the upper face of the flange 18. This scale is preferably sub-divided into (125 divisions, each of these divisions corresponding to one thousandth ofan inch, as will .be readily understood, since each revolution of the block 15 causes it to travel one eighth of an inch, or .125 inch. a

The micrometric adjustment is obtained by rotating the base block 1.5 and observing the readings on the dial 21. The one eighth inch measurements are readily observable from the scale on the indexpost 19. A series otmeasuring rods 25 of various lengths and preferably having their lengths marked on them, may be screwed together, and into a threaded pocket 26 in the bottom of the recess 17. Preferably these rods run from '12 inch lengths to one-half inch lengths, finer final adjustments'being obtained by rotating the block 15. Each of the rods includes a threaded extension27 at one end adapted to be screwed into a corresponding socket 28 in the other end of an adjacent rod, the extension 27 of the lowermost rod entering the socket 26 as above noted. When gauging the height of a tool such for instance as the planer tool 11, the base blockunit 12, 15 is placed on the table 10 of the machine, with down on to the top the index post set at zero,

er block 18 screwed the lower block 12, pointer 20 of the fianges'of the and in consequence with the post scale at zero. A series of measuring rods are then coupled together, these rods cooperatively measur ng a distance lessthan one-half inch shorter to which the tool is to be set. ing final adjustment the block 15;, this final adjustment being graduated to thousandths on theiparticular scale illustrated and permitting fine work to be done even thoughthe adjustment is ef- The remainfectedthrough the intermediacyofthe rela-.

tivelycoarsely eut screw 16. I j v ltwillbe evident that the particular numberof measuring rods 25 whichmake up a set to go with the tool, and the particular lengths-of these rods, form no part 0f the present invention, land may be infinltely a varied. 1 I have found however, that the use of j that additional rodsof 1 foot length may be used 'if desired.

onerod 11 inches hi h, onel inches, one- 3 inches, one-e2 incilies, two-I-l k inch, and twoe in ch, areparticularly convenient for obtaining'any measurement up to 2 feet, and

may be tightened to clamp the gauge in any desired adjusted position, and the tool 11 i moved donwardly until it contactswith the up ersurface of the composite measuring 1'0 "25, 25. 1

. Obviously, various changes and alterations might be made in the generalformva-nd arrangement of the partsdescribed without departing from the invention. Hence I do not wish to forth, but shall consider myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of the appended claims. j
